Description

Technical Field

[0001] The invention relates to the technical field of mattress materials, in particular to an antibacterial rollable jute layer and a preparation process thereof. Background Art

[0002] The jute layer used in the existing mattresses is made by bonding jute silk and hot melt cotton together through hot pressing. Due to the high hardness of jute silk, the jute layer after hot pressing can still see obvious material stratification, so the jute silk is easy to fall off and delaminate, making the entire jute layer weak. In order to prevent the jute layer from falling off or delaminating, square or striped grids are embossed on one side of the surface. Although the jute layer slightly reduces the phenomenon of falling silk, it looks rough and not delicate. Especially when the jute layer must be rolled into a roll for mechanical automation production, not only does the roughness increase the difficulty of rolling, but the jute layer will further increase the situation of falling silk and delamination during the rolling process. When the jute layer that has been rolled is automatically unrolled by the machine in the next process, it is also easy to fall silk and delaminate, resulting in a lot of defective products.

[0003] In summary, it is necessary to propose an antibacterial rollable jute layer and its preparation process to solve the above problems. Summary of the invention

[0004] The object of the present invention is to provide an antibacterial rollable jute layer and a preparation process thereof, so as to solve the problems raised in the above background technology.

[0007] Preferably, the ratio of jute silk to hot-melt cotton in the heat-pressed bonding layer is 1:9.

[0008] Preferably, the ratio of jute silk to hot-melt cotton in the rollable jute layer body is 3:7.

[0009] Based on the above rollable jute layer, the present invention also proposes a preparation process of an antibacterial rollable jute layer, comprising the following steps:

[0010] S1. The jute and hot melt cotton are mixed in a ratio of 1:9, and the mixture is subjected to a hot pressing process at 180-200 degrees for 5-10 minutes to form a bonded body of jute and hot melt cotton, that is, a hot pressing bonding layer;

[0011] S2. Jute silk is laid on both sides of the jute and hot-melt cotton bonded body in a proportion, so that the ratio of jute to hot-melt cotton is adjusted to 3:7, forming a rollable jute layer body, wherein the hot-pressed bonding layer is located in the middle, and a jute silk layer 3 is provided on both sides of the outside;

[0012] S3. Use dense needle punching technology to puncture and connect the rollable jute layer with jute silk laid out back and forth at a density of 1-2 cm, so as to form a rollable jute layer with full fusion of jute and hot-melt cotton and a uniform and flat needle-punched three-dimensional cross, with a gram weight of 200-450 grams per square meter.

[0013] Compared with the prior art, the beneficial effects of the present invention are as follows: the surfaces on both sides of the rollable jute layer body of the present invention are flat without checkered or striped imprints, making the entire jute layer appear soft and delicate, and at the same time, it is a needle-punched three-dimensional cross structure, so that the jute and the hot-melt cotton are fully cross-fused, and the entire jute layer is integrated, there is no material stratification phenomenon, and there is no jute silk falling off and delamination. The entire jute layer is strong and tear-resistant. During mechanical automated production, the jute layer can be easily rolled up without losing silk or delamination. When the next process uses a machine to automatically unfold the rolled jute layer, it is also very neat and smooth without losing silk or delamination, which greatly improves the production yield.
